Content server 500 error with ODPS access

Hi,

I am running a clean 3.10 (not an upgrade) 64bit for windows version of Calibre.

I am running the content server without a user/password setup.
About 50% of directories on the OPDS return a 500 server error but the same view seen from the web shows without a problem.

For instance 5 star rated books. Show fine at http://192.168.1.10:8080/#library_id...&sort=tags.asc

But return an error when browsing through FBReader (or same URL in browser, taken from the access.log)

Since so many authors/series (but not all) it seems to be connected to some metadata rather than an overall problem with the content server.

This is from the error log:
calibre server listening on 0.0.0.0:8080
OPDS feeds advertised via BonJour at: 192.168.1.10 port: 8080
Unhandled exception in state: State: _job_done Client: 127.0.0.1:55462 Request: GET /opds/category/726174696e67/49313a726174696e67?library_id=Calibre_Library HTTP/1.1

TypeError: cannot concatenate 'str' and 'NoneType' objects


Googling this error simply points to update Calibre, but I am already on the latest release.

Any ideas?

Thanks,

That error indicaes the book entries in you calibre database are missing a UUID, which should be impossible. Have you modified the calibre database manually, or are you running some third party plugins?

Yes, I am running the Goodreads plugins since they have all the series correct and in order.

About 13% of my books are missing a UUID (search for uuid:false)

I am also using the "Find duplicates" plugin. But I don't think that plugin has affected around 13% of my books. More likely culprit is the Goodread since I have used it to tag all my series.
